Strong High-Strength Double Sheath Armored GYTY53
Description
The cable configuration involves fibers housed within a flexible tube made of high-strength plastic, filled
with a water-resistant compound. Positioned at the core is a steel wire, sometimes coated with polyeth-
ylene (PE) for higher fiber count cables, serving as a metallic strength member. Surrounding this member,
tubes and fillers are stranded to form a compact circular core. To safeguard against water ingress, the cable
core is filled with the filling compound and covered by a thin PE inner sheath. Following this, a PSP layer is
longitudinally applied over the inner sheath, completing the cable with a protective PE outer sheath.
Application
1 Tailored for outdoor distribution, ensuring durability in various conditions.
2 Compatible with aerial, duct, and direct burial installations.
3 Designed for both long-distance and local area network communication needs.
Characteristic
1 Excellent mechanical strength and temperature resilience.
2 Hydrolysis-resistant high-strength loose tube construction.
3 Specialized tube filling compound ensures critical fiber protection.
4 Balances crush resistance with flexibility for versatile use.
5 Ensures watertightness through multiple measures:
* Central strength provided by steel wire.
* Complete cable core filling with loose tube filling compound.
* APL moisture barrier.
* PSP layer for enhanced moisture resistance.
* Water-blocking material for added protection.
